Gunman in Edison shooting had been reprimanded by boss, source says

The Southern California Edison employee who killed two managers and wounded two others last week had recently been verbally reprimanded by his boss, according to a law enforcement source.

The source, who spoke on the condition of anonymity, told The Times that detectives are still investigating and are not sure the reprimand was a motive in the shooting. The source did not identify the supervisor involved or say if it was one of the managers shot by the gunman.

Andre Turner, 48, fatally shot himself last Friday after selecting a few targets from Edison management and walking up to them and shooting them. Robert Lindsay, 53, and Henry Serrano, 56, died in their offices.

“Witnesses describe him as calm and calculated, even making small talk between the shootings,” the source said.

The source told The Times the reprimand was for a minor incident but said the Norco man may have considered it more serious.

Angela Alvarez, 46, one of Turner’s bosses, remains hospitalized; but Southern California Edison said Abhay Pimpale, an independent contractor working for Edison, was well enough to be released from the hospital.

According to a law enforcement source, Turner exhibited no unusual behavior on the morning before the shootings and that initially people were not even aware of the event unfolding.

Hundreds of employees gathered Sunday for a vigil outside the Edison facility in Irwindale.

"We are all so shaken by what happened. About 250 employees came together to just commune over such a sad, sad event," said company spokeswoman Vanessa McGrady.

"We are just brokenhearted and our hearts go out to all the families that are affected," she added.
